Anode for a flat display screen

A fabrication method of an anode (5) of a flat display screen, including the following phases:

• 1) forming, on a substrate (6), three series of anode conductors (9) in alternated parallel strips (9g, 9b, 9r), two first interconnection paths (12, 13) of the first two series of anode conductors (9g, 9b), first two connection pads (15,16) to the first two paths, and pads (14) of a third series of anode conductors (9r);
• 2) depositing an insulating layer (8) over said substrate (6), conductors (9), paths (12, 13) and pads (15, 16, 14), and etching, in said insulating layer (8), holes (23) to receive phosphor elements (7) in register with the anode conductors (9), and windows (25, 26, 27) in register with the pads (15, 16, 14);
• 3) forming a third interconnection path (21) of the third series of anode conductors (9r) and a third connection pad (22) over said insulating layer;
• 4) electrically coupling said third connection pad (22) to said pads (14) of said third series of anode conductors (9r);
• and,
• 5) depositing phosphors (7) over the anode conductors (9) in the holes (23) of the insulating layer (8).
